source code check ins
-
I have a "friend", whose working on a project implemented in a coffee flavored language. My friend has observed that the project has an extreme rate of checkins - update once, and 10-15 minnutes later there will frequently be 20 or 30 more updates to grab. Making my friend think that the project has people checking in whenever they save a file. A side effect seems to be that you can update, have a broken build, report it as broken, only to have the "fix" mysteriously checked in while you're emailing the problem in. Another update, and the build is "fixed". Has anyone else heard of this? How often do you check in?

Your friend's friends needs DVCS (i.e. Mercurial / GIT), so that they can check-in as many times they want without breaking the built, and still get the statisfaction of check-ins. and once their code works then, they can push it to the server.

No, looks like a bad habit to me.

When the issue / work item I am working is done with minor functional testing.

At work, for bugs, a check-in is usually the full fix for a specific bug. For new functionality, a check-in is usually a tested, wont-break-build version that represents a sub-unit of the whole functionality.

We only check in code when it's been tested and is ready to move to the production server.
This should only be true if you're working on the main development trunk... otherwise, why would you move your code so sparingly? What if your machine crashes or gets a virus? Work on a branch and check in as often as necessary.

When using centralized SCS (TFS, SourceSafe, SVN) I normally checkin after a unit of work has been completed. This is basically a small feature or a fix. When using distributed SCS (GIT and mercurial), I check in as often as I can sometimes even after modification of a single file. Of course, I push it to the centralized build server only after a unit has been completed.

You can do frequent check-ins on centralized servers too, just need to branch your work so you don't affect the main source trunk.

See my comment above in regards to branching.

We have used IBM Rational Unified Change Management, which is very overwhelming at first, and a bit heavy on process. In a large organization, I think it's the only way to go. Each developer gets their own "view" of the source. I can check-out and check-in my source all I want in my view. After I am done developing, testing I "deliver" to the integration stream that everyone on my team is working on for the current project. Before I finalize the delivery, I can actually build from the integration stream to verify that I didn't break the build. If anyone tries to update their source during that period, they will get the code at the point before I deliver. If I find I have made a mistake, I can easily back-out the check-in, and try again once I have resolved the issue. Finally, the changes from the integration stream can be delivered up the chain to the base stream.

Branches are easy to create, very easy... the problem is Merging which almost all the SVN / CVS lacks (It's the design flaw). and it requires lot of manual work. :)

Oooh - the days of ClearCase (I think this is what this used to be called). I remember all that now! Yeah it was a bit over blown, but it did have a lot of nice features once it was all set up correctly. But I think all the developers bitched about the amount of time it took to get used to it. It was also a nearly full time job to babysit the server to keep it up and running and happy :)

I've found merging in SVN less hassle than CVS. But it's still a bit of a PITA.

For me even TFS failed many times to merge automatically after adding few lines on the file which someone else is also working. It will get confused if you move a block of code, because SVN/TFS/CVS doent keep track of changes, they keep copies of files.

I use svn... Once you get the hang of doing merges... Not very hard at all...

Mostly intentional. It starts at Int32.MinValue :)

looks like bug to me, if you are on the post above and press ctrl + ->, they are messed up but if you are on the post below and press ctrl + <-, then looks ok.

We do have other methods of backup in case a machine crashes. But you have a point. It's probably a lot easier to recover from some kind of failure if you use those features in your source control instead.
Plus if you use multiple machines, it is way easier and faster to move your source around.... Since once you've done the initial checheckout, you just have to update from the repository (get changes instead of whole thing).

If you're using TFS, you can shelve your changes.

Define "messed up" and "ok". I know that IE has a bug where OL items will all get a value of 0 and interacting with the page a bit will restore the numbers to their correct values.

I think I need to rename the app I'm working on to "Free Unified Change Keeper". :cool:

That seems wrong on so many fronts. IMHO, a checkin should reflect a bug fix or a (partial or complete) feature implementation. The important thing is, a checkin should be revertable without breaking the build or run-time functionality. We use TFS's shelveset feature all the time, allowing us to preserve (and share for code-review) partially completed pieces of work without fear of losing data or corrupting the codebase. Looks like some (gently proffered) developer education is appropriate. :) /ravi
